Pulstar Spark Plugs

[SoloSK71]

So the fact that they used a dyno to show more HP is what? False?

And a 30 day money back guarantee as well?

Anyone personally installed these and had problems?

I never found anything better than ac/delco plugs in a gm car.

Yep and some aftermarket plugs will cause a misfire and throw codes in your GM vehicle. Have seen it several times. guys would come in and have a code for misfire on their GM car/truck after replacing the stockers with aftermarket brands.

When you're running a coil per cylinder you aren't really going to get any better spark than what the car comes with stock. If you are keeping you car stock, stick with the Delco platinums.

The reason so many LSX people run NGK TR55's/TR6's is the fact that they have a larger copper core than a platinum plug. The copper won't last as long as platinum, but at the same time copper dissipates heat better than platinum, and should deliver a more reliable spark. Like CamaroSpike said, you can generally run em 20k-30k miles. Plus, at less than $2 a plug, theyre dirt cheap.

Plus, I don't care what GM says about 100k miles, I would change the stockers out at 50k.

necro haha i forgot all about this thread and im the one that started it :O...idk ill try it in my 4 banger first...it will be cheaper that way...if i see improvement i may decied to put it in the moster

I'm switching to sonic sparks www.enginebrain.com. I used them in my Harley's and you could feel the seat of the pants pick up they gave you. I know alot of people are saying stay with what you've got but he'll do the improvements to any spark plug you want. it just so happens he told me without asking that he's using ac delco for the 2010 camaro. I will be getting them late this week or early next week. I'll know right away if it's going to cause issues. Other wise I'm going to track mpg for improvements. I'm not dynoing until I get some other upgrades. PM if your interested in my results. otherwise visit his website.

I hate to tell you guy's but as long as there is enough spark to start clean combustion anything else is a waste. The bottom line is that no spark plugs produce power. some say they can "feel" the different but ass dyno's suck and are only comparable to bench racing.
Once combustion is started gas expansion begins and thats what makes power. As long as your spark produces a clean flame anything else is crap. More spark energy does not equal more power.

The AC/Delco will last about 100k miles, the aftermarkets probably won't. I put Splitfires in my 1993 Camaro, took me over 2 hours to install (the 2010 is 100% easier to work on), spent allot of $$$ and no noticeable performance gain. The electrodes wore fairly quickly. Wasn't worth it for me.

Watch out on dyno confirmations on changing to new plugs. I have seen dyno data showing noticable HP increases by just replacing the stock plugs with new stock OE replacements. The HP increase comes from changing plugs and not from anything magical about better plugs.

If a simple plug change would yield more power, don't you think GM would be doing it? It's much simpler than redesigning cylinder heads, cam profiles, etc.

it isn't promoting more spark just a better spark/burn. I know my mpg increases when I use these plugs. some say they can "feel" the different but ass dyno's suck and are only comparable to bench racing. you lost me here?

That is like using Nitrogen in your tires instead of ambient air. Waste of money.

and in most cases, its not a gain of power, its re-gaining LOST power.

not when it costs $200 bucks for a set of plugs. there are more than enough customers out there that would NOT want to pay $200 more for "better" spark plugs. there will be plenty of buyers of the Camaro who wont change the plugs at all during the life of the car.

he's basically saying that the people who say they can "feel" an increase of 5-10hp are full of . and I agree with him. "butt dyno" aka going by the seat of your pants isnt an accurate way to gauge a mod. a lot of things have a placebo effect. people think it is doing something whether it is or not.

depends on the type of tires and what the car is being used for. and if you just happen to have a nitrogen tank in the garage....lol

[SoloSK71]

So is the consensus that any dyno gains are purely from putting in new spark plugs? Regardless of age, driving habit, type, new sparks plugs cause dyno gains?

A new set of NGK spark plugs is over $160 anyway?
